EDWARD A. SCHREIBER, OF CHICAGQ ILLINOIS.

VESTIIBULE-DIAPHBAG-M FOB, RAILWAY PASSENGER -CARS.

To all whom it may concern Be it known that I, EDWARD A. SCHREIBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in vestibule-Diaphragms for Railway Passenger-Cars, of whichthe following is a specification.

My invention relates to railwaycar vestibules, and has for its object to provide a bellows diaphragm for car vestibules composed largely, preferably wholly, of metal, which will be inexpensive to manufacture, light in weight, strong and durable, which will be so constructed as to accommodate itself to the various movements of the cars between which it is placed, and which, for these and other reasons, can be employed to advantage in place of the canvas diaphragms commonly used at the present time. The bellows diaphragm of a car vestibule must be capable, in the first place, of readily collapsing and expanding as a whole when the face plate is moved toward or away from the car. In rounding a curve the diaphragm has to collapse on one side and expand on the.other. Besides this, the diaphragm of a car vestibule should be capable of absorbing the up and down and transverse vibrations of the cars to which they are attached so as to prevent, or at least to minimize, the chafing of the face lates. The fact is that the adjacent ends o two cars in a railway train in motion frequently shift their relative positions with respect to each other due to curves and differences in level of the rails, and besides this are subjected to continual -vibratory movements both vertical and transverse due to the elasticity of the rails and of the springs on which the cars are mounted, inequalities in the track and other causes. My mvention, 1n substituting metal for cloth in the construction of a vestibule diaphragm takes account of thesemovements and provides a structure which, while being less expensive and more durable than the canvas diaphragms, will, to all intents and purposes, be as flexible and as capable of accommodating itself to the shifting and vibratory movements of the car as are the familiar type of canvas diaphragm.

The invention is illustrated, in certain Specification of Letters Patent.

Application filed January 12, 1814. Serial No. 811,598.

Patented July 28, 19 14.

preferred constructions, in the accompanying? drawings whereinlgure 1 is an end elevation of a railway car furnished with a vestibule diaphragm embodying one form of the invention; Fig.

2, a sectional plan taken on line 22 of Fig.

1; Fig. 3, a detail plan section like that-- a sectional view on line 88 of Fig. 9, and

Figs. 9 and 10, sectional views on lines 9 9 and 1010, respectively of Fig. 8; Fig. 11, a view, in perspective, of one of the top panels; Fig. 12, a fragmentary view, in perspective, of one of the side panels; Fig. 13, a similar view of another side panel, and Fig. 14, a view, in perspective, of a modified construction in which the diaphragm is made up very largely but not wholly of metal parts.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to- Figs. 1 to 13 inclusive;

25 designates the end wall of a railway car, 26 the flooring of the car and 27 the diaphragm face plate of the vestibule. The diaphragm is made up, in the preferred construction shown in these figures, of two sets of side panels, a set of to anels and two sets of corner panels, all oFslieet metal, the panels of each set being hinged together along their meeting edges. panels are mounted upon sets of arched rods,

Preferably the the hinges being formed by interlocking beads.

In the construction shown each set of side panels comprises three panels 28 (Fig. 12) each formed with a large bead 29 on one edge and a smaller head 30 on the other, a panel 28 (Fig. 13) formed with oppositely turned beads having the same 'diameter as the smaller beads 30 of the pauels 28, and a pair, of attaching members or panels 33 having beads 34 of the same diameter as the in Figs. 2 and 3.

The top structure consists of attaching members 37 37 secured to the end wall of the car-and to the face plate respectively,

and formed with beads 38 (Fig. 9); three panels 39 (Fig. l 1)each formed at one end with a small head 40 and at the other end with a larger bead 41, both beads being bent in the same direction from the plane ofthe panel; and a single panel 39 which is like the panels 39 except that its two beads 42, 43 are bent in opposite directions and are of the same diameter.

p The spaces between the side panels and the top panels are closed by two sets of corner panels having the same bellows-like collapsing relationship with each other as the side and top sets. The corner set con s'ists, in each case, of attaching members 44, 44 (Figs. 4 and 7); three panels 45 (Figs. 5 and 6) each formed with a large head 46 and a smaller bead 47 and a single panel 45 like the panels 45 except that its beads 48, 49 are of the same diameter and are bent in opposite directions from the plane of the panel. It will be understood that the difference in the form of the elements 28, 39 and 45 from thecorrespond ing panels 28, 39 and 45 is necessitated by the anchoring of the attaching members 33, 37, 44 to the end'wall of the car and the face plate. Different expedients might be usedfor accomplishing the desired. end but the one described I consider the most advantageous.

Preferably the corner panels 45, 45 have .an overlapping relationship with the side panels and top panels. As shown in Fig. 5

each panel 45 -(and the same is true of panel 45 which difi'ers from panel 45 only in the respect noted) is formedwith an extension 50 which extends under the corresponding top panel 39 and, at the other extremity,

with an extension 51 which overlies the corresponding side panel 28; the extension 51 being bent twice upon itself so as to provide a U-shaped part 52 adapted to receive and hold in place the upper end of the side panel (Figs. 6 and 10). The beads 41 of each of.

diaphragm above described is constructed entirely of metal parts and forms an en tirely closed structure, relatively weathers One side can collapse While the other expands. The parts are fitted together loosely enough so that the ,vertical, and transverse vibrations of the car are absorbed and chafing of the face plates prevented. At

the same time the structure can be made more cheaply than the ordinary canvas diaphragm and will be much more durable.

In Fig. 14 I have shown a modified construction consisting of side panels 55 and a set of top panels 56, the panels of each set being united together in hinged relation by interlocking beads as in the construction previously described. In this case, however,

instead of using the continuous arched rods I preferably use straightvertical rods 57 for the side panels and straight horizontal rods 58 for the top panels. ploying metal corner panels for closing the corner spaces this construction employs fabric .corner pieces 59 each of which is riveted to a pair of side panels and a pair of top pan'elsandwhieh may be made of waterproof vduck or other suitable material. While I have described my invention as embodied in certain preferred constructions,

Instead of em it' will be understood that modifications might be made without departing from the principles of the invention. Therefore I do not wish to .be understood as. limiting the invention to the precise constructions, arrangements and devices shown except so far as such constructions, arrangements and devices are made specific limitations in certain of the claims herein.
